Dog Heatstroke Survival Guide

 

Know how to treat and prevent this dangerous condition.

What is heatstroke?

 

In simple terms, heatstroke occurs when a dog loses its natural ability to

regulate its body temperature. Dogs don't sweat all over their bodies the

way humans do. Canine body temperature is primarily regulated through

respiration (i.e., panting). If a dog's respiratory tract cannot evacuate

heat quickly enough, heatstroke can occur.

 

To know whether or not your dog is suffering from heatstroke (as

opposed to merely heat exposure), it's important to know the signs of

heatstroke.

 

A dog's normal resting temperature is about 100.5 to 102.5 degrees

Fahrenheit. Once a dog's temperature rises above 105 degrees, physiological

changes start to take place, and the dog begins to experience the effects of

heatstroke. At 106 to 108 degrees, the dog begins to suffer irreversible

damage to the kidneys, liver, gastrointestinal tract, heart and brain.

 

If a dog is experiencing heatstroke, you may observe excessive panting;

hyperventilation; increased salivation; dry gums that become pale, grayish

and tacky; rapid or erratic pulse; weakness; confusion; inattention;

vomiting; diarrhea; and possible rectal bleeding. If the dog continues to

overheat, breathing efforts become slowed or absent, and finally, seizures

or coma can occur.

 

The amount of damage a dog sustains when stricken with heatstroke

depends on the magnitude and duration of the exposure. The longer and

more severe the exposure, the worse the damage will be.

What to do

 

1. Pay attention to your dog. Recognizing the symptoms of heatstroke and

responding quickly is essential for the best possible outcome.

 

2. Get into the shade. If you think your dog is suffering from heatstroke,

move it into a shaded area and out of direct sunlight. Apply cool water to

the inner thighs and stomach of the dog, where there's a higher

concentration of relatively superficial, large blood vessels. Apply cool

water to the foot pads, as well.

 

3. Use running water. A faucet or hose is the best way to wet down your

dog's body. Never submerge your dog in water, such as in a pool or tub -

this could cool the dog too rapidly, leading to further complications,

including cardiac arrest and bloating.

 

4. Use cool - not cold - water. Many people make the mistake of using cold

water or ice to cool the dog. When faced with a dog suffering from

heatstroke, remember that the goal is to cool the dog. Using ice or

extremely cold water is actually counterproductive to this process because

ice and cold water cause the blood vessels to constrict, which slows blood

flow, thus slowing the cooling process.

 

5. Don't cover the dog. One of the keys to successfully cooling your dog

is ensuring the water being placed on the dog can evaporate. Never cover an

overheated dog with a wet towel or blanket. This inhibits evaporation and

creates a sauna effect around your dog's body. Likewise, don't wet the dog

down and put it into an enclosed area, such as a kennel. Any air flow during

the cooling process is helpful in reducing the dog's body temperature.

Sitting with the wet dog in a running car with the air conditioner blowing

is an ideal cooling situation.

 

6. Keep the dog moving. It's important to try to encourage your dog to

stand or walk slowly as it cools down. This is because the circulating blood

tends to pool in certain areas if the dog is lying down, thus preventing the

cooled blood from circulating back to the core.

 

7. Allow the dog to drink small amounts of water. Cooling the dog is the

first priority. Hydration is the next. Don't allow the dog to gulp water.

Instead, offer small amounts of water that's cool, but not cold. If the dog

drinks too much water too rapidly, it could lead to vomiting or bloat.

 

8. Avoid giving human performance drinks. Performance beverages designed

for humans are not recommended because they are not formulated with the

canine's physiology in mind. If you can't get an overheated dog to drink

water, try offering chicken- or beef-based broths.

See a veterinarian

 

Once your dog's temperature begins to drop, cease the cooling efforts and

bring the dog to a veterinarian as soon as possible. Your dog's temperature

should be allowed to slowly return to normal once cooling has begun. A dog

that's cooled too quickly may become hypothermic.

 

Even if your dog appears to be fully recovered, the veterinarian needs to

check to determine if the heatstroke caused any damage to your dog's

kidneys and liver. The effects of heatstroke can continue for 48 to

72 hours longer, even if your dog appears normal.

 

William Grant, DVM, a veterinarian for 20 years and former president of the

Southern California Veterinary Medical Association, has treated hundreds of

cases of heatstroke, ranging from mild to fatal.

 

According to Grant, the most common cause of death following heatstroke is

disseminated intravascular coagulopathy (blood coagulating throughout the

body), or DIC, which can occur hours or days after the heatstroke episode.

 

DIC can also be caused by pyometra or septicemia, but Grant says

heatstroke is the most common cause. "Once a dog develops DIC, it may

bleed in the thorax, abdomen, nose and intestine," Grant says. "Once

the blood-clotting factors are consumed, there is an inability of the

blood vessels to prevent leaking; the condition is almost always

fatal." For this reason, follow-up veterinary care is essential

following a heatstroke episode, even if your dog seems to be completely fine.

 

Prevention is the best medicine

 

The best treatment for heatstroke is prevention. Especially during the

summer months, it's essential to be aware of the potential for heatstroke.

Knowing the signs of heatstroke, and taking the necessary steps to prevent

it, will ensure your dog can have a safe and active life year-round.
